I tried to make a group/community to help with his obvious lack called #discuss - made to highlight posts of interest but aren't by the people who are promoted or the 'inner circle jerk' or whatever you want to call it lol. 

But communities / groups are somewhat defunct and fiddly.

I wonder how you ould automate it, cos obviously this could easily be gamed, and would also highlight posts of no interest but with lots of replies. (Could be eg a word count? I don't know + some element of WoT? ... I don't know)
